Abstract

Dispositif de retrait de tissu comprenant une aiguille creuse, un transducteur ultrasonore destiné à faire vibrer mécaniquement l'aiguille, un tube d'aspiration en communication avec l'aiguille, et un dispositif d'impulsions de vide servant à générer des impulsions sous vide dans l'aiguille. Ce dispositif peut être utilisé pour fragmenter le tissu par phacoémulsification, pulsation sous vide, ou les deux.
